WuWilan11 Holland Avenue, Ottawa, Ontario, Canada K1Y 4S1613-688-8959rwu@Abstract This contribution is to propose a unification of sampling rates for 6 MHz, 7 MHz and 8 MHz. We propose to use the parameters of 7 MHz as the base and to adjust the guard bands for 6 MHz and 8 MHz. 7 MHz has the merit that its base sampling rate is 8 MHz which results in rational parameters in both timing and frequencies. This unified sampling rate can simplify the radio frontend design for 3 bandwidths (one ADC/DAC for 3 bands); relax the phase noise/frequency offset limitation for 6 MHz radio; and simplify the hardware and software implementation for MAC and PHY.
